              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Weathered out the entirety of the first half due to thick clouds. At roughly 23:05 we opened for 10-15 minutes to get some quick training in on slewing and rotating (plus finding out that we couldn't even see a 1.14mag star) before having to close again due to the threat of virga.
Opened for the second half around 2 AM, with clouds clearing for long enough to get some data. Humidity began rising fairly quickly and was at 75% by 3 AM. It stayed high for the rest of the night, but was never bad enough to close. Clouds started rolling in again around 5:45 AM, and we closed around 6 AM.
No problems tonight.
